Display method and display device

摘要

A display method of an embodiment (i) determines a suitable length of an off period of an LED in accordance with a gray scale transition time, i.e., a time during which a transmittance of a liquid crystal is being changed, and (ii) turns off a light source for the determined length of the off period in a first half part of a one frame period. This makes it difficult for a halfway change in a gray scale transition to be reflected in a brightness of a pixel. Also, by performing a gray scale transition emphasis process to a display signal when the gray scale transition is caused, it is possible to increase the brightness of the pixel in the midst of the gray scale transition and to reduce a response time of the pixel. As such, it is possible to further improve a quality of moving image display.

主权项

1. A display method, which (i) causes pixels forming a display screen to display information, by driving the pixels in accordance with a display signal so as to modulate, via each pixel, intensity of light emitted from a light source and (ii) blinks the light source in accordance with a frame frequency, the display method comprising the steps of:
finding an average of a response time required for each pixel belonging to a specific area of the display screen to respond to a gray scale transition between a frame and an adjacent frame following the frame; determining, based on the average of response times in the specific area, at least one of a length of an off period of the light source in a first half part of a one frame and a length of an on period of the light source in a second half part in the one frame; and after the gray scale transition, driving, at least in the adjacent frame in which the gray scale transition is caused, the light source in accordance with the off period or the on period determined in length.
